@AA5B So we got the best locks we could get from the supplier, which supposedly are hard to pick, cannot be picked and cannot be copied without a key card (not sure how that works). Our doors and windows are enforced. We had one person comment that he rarely saw houses that were this secure (but then he wasn't a security guy, just a buildings guy). On top of that we have cameras, an alarm system and fog canons.

It would be convenient to have a smart lock, and I would love to be able to detect if doors are locked or open (Having this as a read-only thing would be perfect), but being a software guy I don't trust the lock to not be hacked or simply malfunction. The alarm system (ADC) is already obviously made by amateurs, but seems to get the job done...

Overkill? Definitely! But my wife worked in insurance and is super coloured by the stories she's heard.
